The population with massive waist circumference is increasing in comparison with that with obesity in entire bodies in Korea. It is assumed that prevalence of obesity is closely related with changes in marriage status such as divorce or separation by death, and age, educational background, diet habits and living environment depending on presence or absence of spouses. To identify whether there are relations between spouse, BMI and waist circumference under the conditions such as life cycle age, educational level, income, smoking, drinking and walking controlled, this study used data of national health and nutrition research organized by Korea Center for Disease Control and Prevention. The subjects of the study were a total of 7,178: 3,043 men and 4,135 women whose ages were above 19 and married. As a result of controlling independent variables except a factor of spouse, there were no statistically significant relations between presence of spouse, waist circumference and BMI in men, but odds rate of waist circumference was lower, 0.78(95% CI 0.636-0.954) when the female subjects had no spouse than when they had spouse.

This study aimed to understand the differences in general characteristics, principal diagnosis, injury-related characteristics, and types of transportation accidents between young-old and old-old patients who were hospitalized owing to injury based on data from the Korean National Hospital Discharge In-Depth Injury Surveys. We used a complex sample cross tabulation analysis (chi-square test) and complex sample generalized linear model (t-test). Therefore, the primary focus of healthcare professionals working with the old-old should prevent falls in the home and increase the available medical care, financial aid plans, and psychosocial support for aging. Additionally education on traffic accident prevention and road safety is particularly important for old-old patients.

The first patient of Middle East respiratory syndrome caused by a novel coronavirus infection in Korea was confirmed on May 20, 2015. After that, MERS spread over the country. In recent years, patients of MERS have been found around the Arabian Peninsula and the case fatality ratio of MERS in those area was been reported to range from 30 to 40%. In this paper, we estimate the case fatality ratio of MERS of Korea using data of 186 infections until December 1, 2015. In this study we propose a novel estimator of the case fatality ratio using information of the patients severity condition as well as records on the days of confirmation and death or recovery of the patient. By using publicly available data of the Department of Health and Human Services Centers for Disease Control, we evaluate a performance of the estimator and demonstrate a stability of the estimator from the early stage of the epidemic.

This study was to examine the relationship between suicidal ideation, depression, stress and their parent's socioeconomic status. Nation-wide representative data from the Korean National Health and Nutrition Examination Survey 2009 were used in this study. 904 adolescents with parent were analysed. Parent's socioeconomic status, especially mother's low educational level and the beneficiaries for national basic livelihood security were significant risk factor for adolescents' suicidal ideation. These associations remained significant in multiple logistic regression controlling for all covariates. The findings in the current study support the global literature on the importance of socioeconomic status in promoting adolescent's mental health. Future prevention intervention efforts to improve adolescent's suicide risk will need to take into consideration parent's and household's socioeconomic conditions. Future study is needed to explore the possible proximal risk factors and mediators between parent's socioeconomic status and mental health among adolescents.

Objectives: The purpose of the study was to investigate the relationship between the oral contraceptive pill and periodontal disease in Korean women aged from 19 to 50 years old. Methods: This study selected 1,579 women of childbearing age from 19 to 50 years old from the 5th National Health and Nutrition Survey data analysis(phase 3, 2012) taking the oral examination. The questionnaire consisted of socioeconomic demographic characteristics, health behavior, use of oral contraceptive pills, and periodontal disease. Socioeconomic demographic characteristics included age, marital status, education, monthly income, and vocation. The health behavior included obesity, stress, smoking, subjective oral health status, use of dental floss, tooth brushing, and diabetes mellitus by fasting blood sugar level. Use of oral contraceptive pills was recorded by monthly use and duration. The periodontal disease was documented by yes or no and selected as dependent variable by logistic regression analysis. Results: After revising the taking period of oral contraceptive pill for this study, there was the correlation between the prevalence of periodontal disease and odds ratio(95% CI) 1.288(1.027-1.617). Conclusions: This study will contribute to the direction of policy for an oral contraceptive pill and provide the basic data for counseling for the oral health and the side effects of oral contraceptive pills.

The purpose of this study was to identify the differences in medical care utilization by regional economic status using the National Hospital Discharge Patients Injury Survey. In order to determine economic status of each region, 234 cities and counties were categorized 5 quintiles according to their financial self-reliance ratio. The main results are as follows. First, low economic region has high age-standardized admission rate and standardized mortality rate. Second, of 16 major diseases, cerebrovascular and heart diseases, lung cancer, and stomach cancer reported greater changes in standardized mortality rate by regional economic status. Third, the rate of admission via emergency room in low economic region is higher than that of high economic region. Lastly, in the major illnesses, lower economic status led to an increase in average length of stay. Therefore, In order to bridge the gap in health inequality across regions, a regional medical policy tailored for each region and characteristics of the economic status should be established.

The purpose of this study is to compare factors influencing the quality of life of osteoarthritis patients in urban and rural areas. The data were derived from the sixth Korea national health and nutrition examination survey in 2014 and analyzed using the IBM SPSS Statistics version 21.0 software package considering complex samples analysis. The subjects of study were 599 adults with osteoarthritis over 50 years. The results of the study show that the factors affecting the urban patients' quality of life are healthcare coverage types, knee joint pain, knee ankylosis, hip joint pain, low back pain, limited activities, and subjective health status. The rural patients' quality of life are influenced by knee joint pain, limited activities, and alcohol consumptions. Therefore, the government should create differentiating strategies and approaches, including community rehabilitation programs, to improve the quality of life of urban and rural patients with osteoarthritis.
